The influence of water-cement ratios and alumino-silicate based accelerator on the properties of fiber-reinforced cement composites

Due to more strict environmental protection and greenhouse gas reduction, it is very important for all industries to appropriately manage their energy consumption. Fiber- reinforced cement composites are the popular building materials which consume enormous energy to intensify its chemical reaction during the autoclave steam curing process. Utilization of chemical admixture to replace the conventional energy-driven autoclave steam curing process will support the fiber- reinforced cement composites industry to develop sustainable building materials. In this research, typical and mechanical properties of the air-cured fiber- reinforced cement composites incorporated with alumino-silicate based accelerator were investigated. The results show an excellent positive correlation between the water-cement ratio of the mix design and the mechanical strength which is the optimum water-cement ratio for this FRCC are 0.53. Moreover, the properties of fiber- reinforced cement composites cured by either the autoclave steam curing process or air-curing process are comparable.

Finite Element Modelling and Analysis of Fiber Reinforced Concrete under Tensile and Flexural Loading

Concrete is a material exhibiting high compressive strength but about tenfold lower tensile strength. Its brittle property also prohibits the transmission of stresses after cracking. Thus, steel, polymer, polypropylene, glass, carbon, and other fibers are added to concrete to form fiber-reinforced concretes (FRC) having enhanced mechanical properties. The utilization of fiber-reinforced concrete is widespread. Identifying the mechanical properties of fiber-reinforced cement composites under dynamic loading, establishing relationships between their composition, structure, and properties, justifying the correct mathematical model, and determining its parameters are challenging. Utilizing finite elemental modeling and analysis to comprehend the mechanical characteristics of the FRC addition to concrete bricks has shown considerable benefit. In the present study, polypropylene microfibers are included in fiber-reinforced concrete composites, and their performance is compared to that of unreinforced concrete bricks. Under FEA analysis, three-point bending and uniaxial tensile tests were conducted. The results indicate that using fiber reinforcements increases the tensile strength and endurance of the brick.
